CONTROLLING DEVICE FOR PRINTNG AYPARATUS.

Application filed April 2, 1926. Seria-1 No. 99,362.

This invention relates to improvements in controlling devices;especially controlling devices for printing apparatus.

An object of this invention is to provide a controlling device by whichcharacters arranged in a certain order can be printed in a totallydifferent order or succession, Without alteration of their arrangementin the printing apparatus which enables impressions ot such charactersto be obtained.

A tnrther object of the invention is to provide a controlling device forprinting mechanism in the form of a convenient and effective attachment`for said mechanism capable ot' being utilized whenever required withoutchange of' structure of the printing mechanism. or even rcadjustment ofthe latter; so that when the controlling device is not in actual use,the printing apparatus can be employed in the regular and usual way.

Another object of the invention is to provide a controlling device forprinting mechanism of such rconstruction as to be easy to handle andcertain in operation, and still adapted to permit the printingapparat-us to give a comparatively large output.

Still ther objects and advantages of the invention are set forth in thefollowing description, taken with the drawings; and the novel featuresare delined in the appended claims; but the disclosure is illustrativeonly, and I may vary the details of shape,

size and disposition of parts, without eX- ceeding the scope of theinvention, as indicated by the broad and general meanings ot the termsin whichY the appended claims are expressed.

On said drawings,

Figure l is a top plan ot a controlling device according to my inventionwith the parts in starting position;

Figures and 3 are opposite end views thereof seen 'from the left andright,respec tively ot Figure l;

Figure l() is a bottom shown .in Figure 9; l

Figure ll is a front view; and Figure 12 a top plan of the device withthe parts in final position;

Figurell is-an end view of the holder for the card or sheet to beprinted, seen from theleft tl1ereoi,'as` shown in Figure 12; and

Figure ll isa `section on the line 14-,-14 ot Figure l2. Y

The same numerals identify the same parts throughout.

Referring to the particular construction shown in the drawings, I usethe numeral l to indicate a base or support 1, which has the form of aflat plate of metal or any other suitable material. On the base is 'acarrier 2 in the form of a frame which bears a stencil or shield 3 inthe formI of a' plate secured along one edge to one end' of the framebeyond one side of the basel lfor example, the upper side or edge withreference to the position of the parts shown in Figures` 1, 5 and 1Q. Inpractice', the'operators place will be adjacent-the oppositel edge ottthe base fl to enable him to convenientlymanipw late the carrier 2andthe other parts which the device comprises. The carrier movesl fromone end ot the base l to the other, along a guide bar 4 and it carrieswith it not only the stencil 3, which-is fixed to the can` rier, butalso a card holder 5 which is mounte ed in the carrier, so that it canbe moved towards one side or the other of said carrier when this carrieris in its starting, middle or final position. The stencil plate has aslot therein shown at 6, and an aperture or open ing 7, the opening 6being spaced from the opening 7. I also show at 8 in dotted lines, theposition of a printing plate which will have characters thereon in theform .of letters, words and figures, 'and these characters can bereproduced in a different arrangementen the surface cfa card disposed inthe holder 5 merely "1y exposing a part of these characters insuccession through the openings 6` and 7. The printing plate 8 will bebelow the stencil 3 as shown in Figure 3, for instance. and between thestencil and thersurface of the plate bearingthe characters to be printedis a ribbon 9 similar to the ribbon ot' a typewriter so that when thecard or sheet to be printed is pressed so as to force part of itssurface against part of the surface of the ribbon which is exposedthrough plan of the part lll the opening 6 or 7. and that part of theribbon against the characters on the plate 8. the desired effect on thesurface of the card will be obtained. To this end,y I may make use ot apressure roller .10 mounted upon a shatt 1l. as indicated in brokenlines in Figures 2 and 3. This roller may be so controlled that it isdepressed as required. and caused to act upon the card. so that the cardmakes contact with the portion of the ribbon eX- posed through theopenings 6 or 7. according as either of these openings ma;vv beutilized. The printing plate S will. of course, be mounted in fixedposition on a suitable support. and the roller l() majT be held andoperated by means of any suitable mechanism to cause it to rise andtall. likewise to move back and forth if desired to a certain extent topass over the full width of the openings 6 and 7. Machines which workwith such plates 8 and ribbons 9 and contain pressure rollers 10. are incommon use. and some of them are designated b v the term addressographs.They are employed for various purposes. such as the printing of indexcards. etc.. and need not be further described here. as mv inventionrelates simplv to a controlling device to be used with such a machine bvsecurinfr it to the fiat top or trame-work thereot` in position tocooperate with the plate 8 and ribbon fl. and enable the roller 10forming a part of such machine to be employed in the ordinary way.

The carrier 2 has the form shown in Figures 1. 5 and 1Q. tor example.and is approximatelv U-shaped. the ends ot the arms thereot terminatingin bearings i2 through `which the bar 4 passes. so that the carrier eanslide easilx7 along this bar. Adjacent the opposite edge of the base l,it is provided with rollers 13 to support it above the surface of thebase. and enable it to more easilv trom one end thereof to the other.Starting at the lett. with reference to Figure l.. the movement ot thecarrier Q with the stencil 3 and card holder 5 will be in a straightline until nearlxy the opposite end oi the base is reached. rllhen. aswill be more full)7 described later. a slight lateral movement takesplace also before, the movement longitudinali)7 ot the base l isfinished. For this purpose. the bar It is mounted. so that it can swingto the required extent away trom the adjacent edge of the base 1. It is,theretore. mounted in bearings at the upper ends of links 14, journaledupon a bar 15 below the bar 4 supported in bearings 1G rigid with thebase 1. Hence. when a force is eX- erted sidewise of the bar 4. it canswing outward away from the adjacent edge of the base l to a certainextent and draw the carrier 2 with the stencil 3 and card holder 5 withit.

Adjacent the end ot the base from which the carrier starts is a diagonalslot in the base l which receives an adjustable gauge or stop 18 which'an be secured at variousl positions in the slot. On the top of thc baseadjacent the .slot is a calibrated scale indicated at lf). to indicatethe positions which the stop 1S is to assume under various con ditions.'lhis .stop marks the limit l'or the carrier 2 at one end of' the basel. and its movement at the other end i.s terminated b v a stop 2t) inthe form of an adjustable .screw in a bearing 2l. which can bc held inposition by a lock uut 22. One .side of the carricr has a jnojcction :Z3to enable the operator to seize it between thumb and finger. and movethe carrier towards the stop 1S. The carrier is actuated to traveltowards` the stop Qt) bj' means ot a spring Q4 in the .bar 4. the latterbeing hollow to receive thi.s spring. One end ot the spring is .securedinside the bar el, and the other end is attached to a. pin Q5 in the barl but fixed to one ot the bearings i2. preferably, the bearing beneaththe projection 23. As indicated in Figure l, this bearing may hare aprojection 2G extending through a .slot 2T in the bottom ot the bar orguide l. and to this projection 2li. thc pin '.25 may be .secured inan)v suitable wav. Hence, when the carrier is not held against movement.the .sprintr 2l will act to draw it to the right: until it encountersthe .stop 20.

I shall now describe the construction of the card holder 5 which ismovablv mounted in the carrier 'lhis card holder comprises a plate 2Salong the sidcs of which are upturned fliinges 29. The plate Q8 extendsfrom the stencil Il across the base almost as far as the bar it. and atits corners adjacent the bar el it has upturned perforated lugs formingbearings 30 on the sides of the carrier Q in line with these bearingsil() arc lugs 3l which are perforated to receive the end:s ot aguide-bar 32 passing' through the bearings 3f). and the holder 5 canthu.s .slide in one direction or another. along the bar 339. A bindingscrew li mounted in om` of the lugs ill engages the bar 3Q. and hold,sit against displacement 'lhe bearing 2l() at the right in Figures 5 and.l` is .shown as provided with a jirojcction Ill. similar to theprojection 2li. to enable the operator to .seize the card holder andmove it. Almtting the. opposite' bearing 3f) is a spring 35 coiledaround the guide-har 92 and attached to this bar at its opposite end bymeans of an anchoringr screw 3G. This spring tends to impe] the cardholder towards the .side of thc frame at which is located the projection Q3.

Rigid with our` ot the flanges 20 at the right. of the card holder 5 isa` guide projection 37 which slides through a bearingr opening 38 in oneside ot the carrier i2. The card holder also carries a movable arm orpressure member 3f) which can be raised loo llt)

lill! and then moved downy on top of a card or sheet of material to beprinted, placed in the holder, to secure this spring or sheet inoperative position. This arm 39 is mounted upon a pivot 40, the armbeing movable up and down about this pivot, and this pivot- 40 issecured to af swivel 41, engaging a bearing in a projection 42, which ispart of the thickened edge` 48 ot the plate 28 beneath theguide bar 32.The portion of the plate 28 adjacent the guide-bar 82 is more elevatedthan the remainder of the plate 28, as indicated at 44, and beneath thisraised portion 44 is a transverse connecting bar 45 which joins the twosides of the carrier 2. Resting upon this portion 44 is the liange 46 ofa plate 47 which is disposed between the flanges 29 on top of the plate28, this plate 47 having two openings 48 therein, and being shoulderedat 49. Thus a card of some width can be placed in the holder 5, one edgeabutting the shoulder 49, and the other edge lying upon the stencil 3. Asimilar shoulder may extend across the card holder joining the principalpart of the plate 28 to the portion 44. The extension 46 has slots 50therein, and the holder 5 carriers threaded studs 51 which pass throughthese slots and bear binding nuts 52. By loosening these binding nuts,the plate 47 can be moved towards or from the stencil 3 and fastened inposition by the nuts 52. The edge of the plate 47 adjacent the stencil 3provides a shoulder 53 so that if a card or strip of relatively narrowwidth is to be printed, it is laid in the holder 5 with one edgeabutting the shoulder 58, and the other edge over the stencil 8, and thearm 39 will serve as before to clamp this strip in place. The swivel 41permits the arm to be swung from side to side as this swivel can berotated in the holder 5; while the pivot pin 41 permits the arm to belowered and lifted. A spring may be employed in connection with thepivot pin 41 to move the arm 89 downward and keep it pressed upon thecard Vor the like, inthe holder 5.

The left side of the carrier 2 is provided with a slot 54, through whichprojects a stop 55 attached to the adjustable gauge or stop 18. Thisstop is in the form of a pin which passes through a bore in the stop 18,and it can be adaj usted and held in adjusted position by means of abinding screw 56, and when secured in place, this stop 55 marks thelimit of the movement of the holder 5 to the lett on the base 1. Thestop or gauge 1.8 has a pointed or index projection 57 to enable itV tobe accurately located with rc* spect to the marks on the scale 19, andit is made up ot two members 58 and 59, one above the base and one belowit, each ot these members having guide projections 60 which enter theslot 17. Through the two members 58 and 59 extends a hole 61, the hole,in the bottom member 59 being threaded, and a headed binding screw 62secures the two members together. l lhen one desires to move. this gaugein the slot 17, the screw is loosened to enable the members to slide inthe slot and then tightened to hold it at the point desired. Further,this gauge 18 carries a pivoted catch 68 mountedon a pin 64. The catch63 is in the formell a bell crank lever, one end ot' which entends :intoan aperture 65 in the member 58, but loosely, so that the other arm ol'the catch which is horizontal can be raised. 'Theend ot this arm has ashoulder 66 thereon, to serve as a hook, and a projection 67 tor thefinger of the operator to raise this catch. Ordinarily, the catch willdrop by its own weight to hold the carrier 2 in a position shown inFigure 5 by the shoulder 66 engaging the top edge of the side ot thecarrier 2. But when'this catch is litted by the operator pressing withhis thumb onthe projection 67, the carrier is liberated, as the catchthen clears the edge 68 of the carrier 2. n To check the holder 5 at apredetermined point` when it moves with the carrier 2 as i'ar as thecatch 63 permits the latter, I mount below the base 1, a movable stopwhich projects through an opening 69, a slightdistance above the topsurface of the base 1. The end of the catch which so projects isindicated at 70 and this end is the upturned extremity of a bar 71disposedv beneath the base 1 and attached by screws 72 to an arm 7 8,pivoted on a pin 74, mounted in bearings or lugs 75. This catch is bestshown in Figure 7. Encircling the pivot 74 is a spring 76 which engagesthe down-turned front edge of the base 1 and the lower tace ot the arm78, so as to urge this arm upward and make the end 7 0 project throughthe opening 69. Carried by the arm or lever 7 3 is a pair of perforatedbearings 77, similar to the bearings 75, and mounting a similar pin orjournal 74 on which rotates a roller 78. The screws 72 pass throughslots 79 in the bar 71 and engage threaded holes in the arm 73, so that'by the loosening ot the screws, the slots` 79 permit the longitudinaladjustment ot the bar 71. The base 1 has slots 8() which expose theslots 79, so that. the heads ol the screws can be disposed in theseslots below the'level ot the top surtace o't the base 1. As indicated inFigure 6, the roller 78 projects above the top of the base` 1 through anopening 81. and when this roller is depressed as indicated in Figure 11.the catch compris ing the upturned end 70 ot the bar 71 is depressed, soas to withdraw the stop 70 from the opening 69 and then permit theholder 5 to move farther to the right when the carrier is urged to itsi'inal position.

On the top surface ot the base 1 just bcyond the aperture 81 towards theright of the base, I aix a cam piece 82 having an lll() til incline ordiagonally extending edge 83. This piece is secured to the top of thebase l hv 'fastening means such as screws Sli. The adjacent side ot thecarrier 2 has on its lower t'ace a projection S5. in line with thecrosshar 45. and when this carrier has traveled 'liar enough to theright. to cause the projection .Q5 to engage the dia f fonall}vextending edge Si?, ot the piece S2. a transverse movement ot' thecarrier swinging the guide 4 outward on the links 14 must occur. To gireclearance tor the piece the adjacent side ot thc carrier 2 between thecrossbar 45 and the roller lil on that side. is av little distance abovethe base l. as indicated in Figure 3. The purpose ot' this transversemovement will be described later.

As indicated b v the numeral SG. the bar 4.5 is not straight but has abend therein adjacent the side engaged by the catch G3. On the lowertace of this bar is a downward extending rib indicated at 87 runningalong the edge which is presented towards the stencil plate 3. andbetween the bend SG and the right end ot this bar. this rib has adiagonal surtace or section SS. Then the carrier mores. this rib ST runsin contact with a roller S9 mounted on a pivot bolt 90 which holds it`in horizontal position on the upper tace ot the base l. As indicated inFigures T and S. the pivot holt 90 passes through the base and screwthreads into a link Q1 below the base pivotallj7 held in place hr arivet 92. This link can be moved from side to side to adjust the rollertowards and trom the rib ST. A binding screw 93 passes through a sloty9i in the base l. and screw threads into the opposite end ot the link91. Hence. by tightening this binding screw. the link can be locked inthe desired. position. Isimilar slot 94 through which the pivot bolt 90passes allows mmement of this holty and the roller S9 when the link androller are to be adjusted. The roller 89 by engaging the rib 87 preventsmovement ot the carrier. the holder and the stencil 3 h v swinging theguide 4: outward on the. links 14: until thev cam piece engages theprojection 85. The roller .Q9 so mounted that this roller :Aimuitamouslvreaches the diagonal surface or portion SS ot the rib S7. and thisroller then does not hinder the sidewise movementJ ot the trame, butcooperates with the cam edge S3.

As stated above.` the flanges 29 do not eX- tend entircljv along thesides ot the card holder 5. hut terminate adjacent the slioulder whichruns along the edge ot the raised portion 114. On the top ot thisportion adjacent the swivel 470. l secure by a hinge. a. member 95. Thehinge for this member is shown aty 96. and it may comprise a spring 97to press down upon the member 95. and hold it flat against the top otthe part it of the card holder. At its tree end, the me1nber 05 has adown-turned end 98 which depends far enough to he in line with the endot the stop when the gauge t8 is mored tar enough along the slot 'li' tobriner the stop into position to strike the. downturned end 9S ol thismember. When the holder 5 is pushed to the lett as tar as it will go inthe carrier the end 0S ol' the men'iber 95 clears the side ot thecross-bar l5. and dropsl as low as the top of the plate '178: but assoon as the holder moves in the carrier. Vt'ar enough to bring thedown-t urned end 9S ot the member Sla into engagement with the hend Sti.the top ol the bar at this bend will lift the member For this purpose.the upper surface ot the har at the bend SG mav be rounded to enable itto have the desired etl`eet on the member 95. rllhe rib Si' l'ollows thecontour of the bend .Qt and when the rib at the bend comes intoengagement with thc roller 8f). the carrier does notl more an)v furtherto thc right, out then occupies its tiual position as Figure. '1Q shows.with the carrier abutting the stop screw 2t).

.l may arrange in one ol the links 111. a stop screw 99 which ma)v ahutthe downturned l'ront edge l0() ot the hase l. to limit the swingingmovement ot the guidivt towards the hase. and l may also reces;` thehase in the middle alongthe edge adjacent the stencil 3 as indicated bythe numeral lOl directly7 adjacent the printing plate S.

In operation. suppose it be (le-'ired to print the matter which appearsupon the upper tace ot the plate 8 below the stencil 3. but to changethe order or succession in which the parts ot such mattei' appear. Letit tirst be assumed that certain words or characters are on the uppertace ot the plate 9. as indicated by the nun'ierals l. ll. and lll. andthat it is desired to revere the order ot' Group I and Group ll. and toprint the words made up b v the charm-ters of Group lll not under GroupsI and ll. hut to one side or in line with same. l proceed bj.' tirstputting a card in the holder 5. clan'ipiug it in place by the arm 3f).This card is shown in dot and dash lines and is indicated b r thenumeral 10Q. lt is illustrated as extending from the shoulder 53 out'over the open ing"v G and 7. The operator then takes hold ot theprojection Q3. and forces the carrier to the right unt-il it strikes thegauge i8. The stencil 3 now moves with it. and so does the card holder5. until this holder ahuts the stop Now the stencil covers` Group l. butexposes the characters making up the numbers. or words. or both7 ofGroup ll through the opening Holding the device in this position. theoperator now causes the roller l0 to descend to press part ot itssurface against the card, so as to torce the portion ot the card overthe opening 6 against, the ribbon t), and this ribbon against theprinting plate 8. f Group II is then forced to make an impressionagainst the card 102.

The next position is the position of the parts shown in Figure 5. Thisposition is attained merely by releasing the carrier so that the spring24 in the guide 4 pulls it to the right as far as the catch 63 permits.The

voperator now lays uhold of the. projection 34 and forces vthe cardholder 5 to the right against the stop 70. The stencil 8 now lies insuch position that Group I is exposed; while Group II is covered up, andthe card upon which Group II has been printed near the right end hasbeen carried so far past the printing plate, that the impression ofGroup II on this card is in advance of Group I, but in line with it.Holding to the projection 34, the operator again makes the roller 11descend and Group I isnow made to give an impression in its turn on thelower face of the card 10Q. The two'impressions are in line with eachother, along the top edge of the card, but are reversed with respect tothe order of Group I and Group II on the plate 8. When the card is takenout and turned over, the right edge in Figures 1 and 5 then becomes theleft edge, and the` matter `printed upon it is of course read from leftto right in the usual way. If, for example, Group Ion the printing platereads Joseph and Group II should read Bowles, B 800, the order in whichthese words and numbers would appear ,on the card after printing isBowles70B 800 Joseph.

To complete the operation and obtain an impression of the charactersmaking up the words or numbers or both of Group III on the printingplate 8, the parts arecaused to assume the positions indicated inFigures 11 and 12. For this purpose the operator presses his thumbagainst the projection 67 to lift the catch63. Spring 24: then actuatesthe carrier 2 to move a little bit farther. Before lifting the catch`63, the projection 34 isf released, so that the holder 5 is not heldagainst the stop 70 when the spring 35can force the holder 5 to the lefta little. The carrier then travels `far enough to engage and depress.the portion of the roller 78 projecting through the opening 81, so asto remove the stop 70ffrom. the path of the holder 5. Next, theprojection 85 strikes the cam edge 83 andthe carrier with the plate 3and holder 5 moves laterally, the guide 4 swinging outward as abovestated.` This movement brings the card-102 in such position that theimpressions which it has received from Groups I and II arenow to theright of the plate 8, and have cleared same, and opening 7 of the plate3 has come into position to expose Group III which heretofore in thepositions of the parts shown in Figures 1 and 5 have been entirelycovered by the stencil 3. At the same time,` the movement of the partstransverse of the base have drawn the card `102 with them, so as tobring the impressions received from Groups I and II in lateral alinementwith the top row of characters of Group III. As shown, the opening 7 issomewhat largerfthan the opening 6, and upon roller 10 .again beingdepressed, an impression is obtained from Group III on the card and thisimpression is not below the impressions of Groups I and II, but on thesame line unless, of course, the words or numbers, or both, formed bythe characters of Group III take up more than one line. The order of theparts of Group III is not changed, but the position of this whole groupwith respect to Groups I and II is changed. The characters of Group IIImay set forth the address, occupation, and other fact-s concerning theperson whose name is being index-ed.

The recess 101 is provided for the convenient removal `of the vprintingplate `8 which in machines of the type for which my invention isdesigned, is displaced by moving it forward out of the machine in thedirection of the guide 4.

The gauge 18 and slot 17 are provided so that the position of thepartsadjacent the left of the base 1 can be accurately obtained according tothe number of characters in Group I which is Lto `be covered when thestencil iirst exposes Group II `through the opening 6. If Group Ipresents the first name of a person of say eight characters,

the index projection 57 of the gauge and stop 18 should preferably beopposite the numeral 8 cnthe scale and for long names, meaning thatGroup I contains more characters, the gauge is simply moved along theslot opposite the higher numbers of the scale. Where thegauge isadjacent the lower numbers, the stop 55 would not strike the adjacentflange 29 of the holder 5, because this flange does not extend farenough towards the cross-bar 4:5. Hence, I provide the member with thedown-turned end 98 to abut against this stop when the conditions of workare such that the gauge must be located adjacent the lower numbers onthe i scale, for proper results.
